Does Xerces 1.1.1 support PUBLIC identifiers

[George Tsai <GT...@scient.com>]

Hi,

I am using xerces 1.1.1 to process some XML documents with PUBLIC
identifiers.
 
<!DOCTYPE DOC PUBLIC "-//MyDOC//MyDOC Rev2 Body Content V1.0//EN" [
<!ENTITY % revision "MyDOC Rev 2">
]>

Xerces throws an exception: 
"The system identifier must begin with either a single or double quote
character." 

The XML authoring tools requires the PUBLIC identifier and is resolved
through a catalog file. I can change the PUBLIC identifier to a SYSTEM
identifier, but it will be less portable given different configurations for
different XML writers.

Any solutions? Thanks.

George

If you look at the productions in the XML specification, you'll
notice that even though you specify a PublicId, you also have 
to specify a SystemId. Since your document starts the internal
subset immediately after the PublicId, this is an error.

Look at productions [28] and [75] in the XML specification for
details.
